Hi.

If the ABS light comes on, then there is definitively a problem that must be corrected. The ABS light turns on for a number of reasons. If the problem started after replacing brake pads and sensors it is usually because of sensor wiring. When abs light is on it means that diagnostic trouble codes are stored in the car computer modules (in both ECM that is the main computer, and also in ABS control module).
If you have done the brake service recently, get back to the garage that did the job and ask them doing a code scanning. Possibly go there while the ABS light is on. The codes will reset after turning on the ignition a number of times if the problem is not there anymore. Wiring problems often manifest themselves only occasionally in consequence of vibration. That is likely your case.

Note: when you go to the dealer for the code scanning mention that the problem started after the repair or you will be charged the standard fee for code scanning (usually half hour labor). Mention that the ABS module may need scanning for codes and go there when ABS light is on. They will use a Tech 2 scanner to pull out ABS codes. A regular OBDII scanner will only retrieve codes from main computer.

Regards.
